MX.{John H Maddocks - Chief Proving Officer} Handwritten: 658 also 1113 WEIGHT ANALYSIS The following is the present position of the Weight Analyses that we have been carrying out:- Completed Bentley Oldsmobile Wraith Chassis Chevrolet engine. In Progress. Vauxhall Car. Packard Suspension P.III. Engine Unit. We find that the pictorial summary of the parts is of great value in helping to simplify projects. When we issued the Bentley book we asked for cost figures to be obtained and inserted in the book against the relevant pieces. It may be argued that these figures are out of date, but they should at least give a rough comparison of the relative cost of various pieces in the chassis. Also, they will be the only cost figures available for the next six months, as Wraith figures cannot very well be established until production are ready to go ahead. We therefore should still like to have the Bentley figures for reference, the material and direct labour cost being separated. We are handing RHC.{R. H. Coverley - Production Engineer} No.8. copy for this purpose. These analyses are costing a certain amount of money to obtain, and it is perhaps worth summarising some of the general information we have so far got out of them on Wraith, dealing with each section of the chassis in turn. FRAME We have measured the stiffness of the Wraith and the Oldsmobile cars. The Oldsmobile is twice as stiff as the Wraith. Its frame weighs 284 lbs, the Wraith frame 410 lbs, i.e., it continued | ||
